Title

Destabilization attack design for discrete time feedback systems

Abstract

Systems theory is used to model many cyber-physical-human systems.  In this work we explore a network abstraction of such models that we use to represent the attack surface of the system.  We then apply results from robust control theory to identify the smallest perturbation on any link of the attack surface capable of destabilizing the system.  In this way we demonstrate stealthy local attacks that lead to system-wide, global failures, creating an effective denial of service for the application.
